Benefits of technology

This patent describes a camera module assembly for use in piping systems. The assembly includes a camera module mounted on a tray that is rotatably supported from a cage skid that is attached to a high-pressure hose. The cage skid is designed to protect the camera module and allow it to rotate in piping bends. The assembly is designed to prevent the camera module from tilting or becoming submerged in fluid. The technical effects include improved protection and alignment of the camera module during insertion into piping segments and easier navigation through bends and obstacles.

Problems solved by technology

However, the hose naturally has some twist as it is advanced and retracted which tends to cause the sled to tip over.
However, friction in the swivel at operating pressure apparently prevents this swivel from performing the desired function.

Embodiment Construction

[0017]FIG. 1 includes several views of a first embodiment 100 in accordance with the present disclosure. Skid nozzle assembly 100 includes a camera module 102 mounted on a camera tray 104 that is rotatably supported from an axle 106 that extends through one end of a cage skid 108. The cage skid 108 is, in turn, fastened to a tractor nozzle 110 that is attached to an end of a high pressure hose (not shown). Such a hose may be pressurized to somewhere between 100 psi to 20000 psi, depending on the service for which it is designed. The cage skid 108 is preferably made of a central bearing sleeve having three or more radially extending ribs 112 that extend outward from the central bearing sleeve and bend so as to extend parallel to the central bearing sleeve to a point beyond the camera tray. These ribs 112 then reconnect around the camera module 102 so as to present a protective cage structure around the camera module 102. This axle 106 supports the cage 108 and also the camera tray 10...

Abstract

A camera skid and thrust nozzle assembly for supporting a camera while being positioned in a tubular pipe or conduit spaced. from any wall of the conduit and permitting movement of the assembly along the conduit. The assembly includes a cage rotatably fastened to a high pressure fluid tractor nozzle, wherein the cage can rotate about an axis through the tractor nozzle. A camera support structure is fastened within the cage for rotation of the support structure about the axis independent of rotation of the cage. The camera support structure has a weight attached thereto for urging rotational orientation of the camera support structure within the cage according to a sensed external gravitational force on the assembly.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of priority of U.S. Provisional Application No. 61 / 804,639, filed Mar. 23, 2013, and No. 61 / 912,458, filed Dec. 5, 2013, both entitled Camera Skid Tractor Nozzle Assembly. These applications are incorporated herein by reference in their entirety.BACKGROUND OF THE DISCLOSURE[0002]A high pressure rotary nozzle and tractor device is disclosed in U.S. Patent Application Publication No. 20120205405. A high pressure fluid switching valve tractor device for use with a nozzle is also disclosed in U.S. Pat. No. 8,667,987. These publications are hereby incorporated by reference in their entirety. Such nozzles and tractor devices are particularly well suited to industrial uses where the operating parameters can be in the range of 1,000 to 40,000 psi and flow rates of 5 to 150 gpm, and when rotary nozzles are employed, rotating speeds of 10 to 1000 rpm or more may be needed.[0003]For inspection of sewer lines and o...
